Out of the 3 my vote goes for JBL X333.
Wonderful HU, looks better than both the other. Sounds a lot better than this entry level pio (sony isin't in contention here). Moreover, X33 has 3 preouts that enables future expansions easy. Even the built quality of X333 is better than the other 2. Most importantly hear with your own ears and then decide.
The only zone in which this pio might score over X333 is the remote. X333's remote looks just like a cheap chinese toy but works perfectly without a fail.
